K&F Concept 77MM NANO-X Pro Brass Frame Black Mist 1/8

The K&F Concept 77mm Black Mist 1/8 Filter (Nano-X Pro Series) features a brass CNC frame, ultra-low 0.15 reflectance coating, and 36-layer nano protection on AGC optical glass for soft cinematic diffusion. It minimizes ghosting, smooths skin textures, and adds a dreamy glow to portraits and night shots while preserving detail, with water/oil/scratch resistance for durable, easy-clean performance.

This professional-grade diffusion accessory is engineered for cinematic photographers and videographers, blending subtle atmospheric haze with high-fidelity optics to elevate portraits, street scenes, and low-light footage. Its ultra-low reflectance coating effectively suppresses flare and ghosting from intense light sources, ensuring natural mist diffusion without color casts or veiling glare. The 1/8 density delivers a gentle soft-focus effect that delicately reduces skin imperfections while maintaining sharp subject details and overall contrast. The precision CNC-machined brass frame provides superior thread engagement and impact resistance, with a matte black finish to minimize reflections. Protected by 36-layer nano coatings, it repels water, oil, scratches, and mildew for effortless maintenance. Included suede pouch ensures elegant, scratch-free storage, making this filter a reliable companion for on-location shoots.
